Home » Emergencies » Water Leak Water Leak If you think you may have a leak in your home we can help you locate it. We recommend you turn off the stockcock and if you are unable to locate it please contact us and we will instruct you over the phone. A stopcock looks like a tap, but without an outlet spout. It will be situated between two lengths of pipe, acting as a connector. This allows the stopcock to block the flow of water when it's closed off. You're responsible for repairing any leaks you find on the pipework inside your home.
